ill-SIDED CURVED-WALLED VESEEL.

Application filed December 1, 1913. Serial No. 803,874.

To all whom it may concern: Be it known that I, JOSEPH DISTER, a

citizen of the United States, residing in Walled Vessels, of which thefollowing is a specification.

This invention relates to an improvement in the art of transparentsided'curved walled vessels, and the invention consists in making thewalls of the vessel of a sheet metal blank into which isset a flexibletransparent window seamed into place while the sheet is in the-flat andthereafter curved into form and finished; and in the product or finishedarticle thus 'made, 7

In the accompanying drawing which forms a part of this specification,Figure 1 is a section of the sheet metal vessel Wall shown in the flatand formed with an aperture having shouldered edges ready to receive theflexible transparent sheet; Fig. 2 is a similar section with theflexible transparent sheet added and showing the shouldered edges turneddown solidly upon sa1d transparent sheet; Fig. 3 is a similar sectionalview of the composite wall showing the salne curved into form and itsends united by a side seam; and Fig. l is a view of the completedvessel.

Heretofore, the worker in sheet metal, in the manufacture of the largeline of articles, like cracker boxes, candy boxes and display boxes ingeneral, that require to have a transparent side through which the con:

tained goods may be seen, has felt obliged to make the vessel containingthe transparent window with a flat side and this has generally resultedin such packages or vessels being made of a rectangular term, involvingthe expense or manufacture cident to such rectangular form and relativgreater than the cost of making the cylind "c or curved form 011'.vessel. in the present invention a means is offered whereby such vesselsbe made with curved walls following in the main the usual processesemployed in the manui acture of cylindric walled sheet metal ware.

In the said drawing, A is a flexible sheet of tm such as is ordinarilyused in the manufacture of tin cans and sheet metal ware. This blank,while in the flat,-is perforated with a large window aperture B, theedges of which are folded outwardly to form the double thickness C, andthe shoulder flange D. The ends of this blank are formed with the usualhooks E, E, to unite them together. While thus still in the flat atransparent sheet of flexible material F, as for example transparentcelluloid cut to the right form and size, is laid into the seat formedby the shoulder flange D, and said shoulder flange is then turned downsolidly upon it, after which the sheet is in such condition that it maybe and is curved into the form shown at Fig. 3 of the drawing, the endsof the sheet being seamed together to form the body of the vessel whichis afterward provided with a bottom G and top of suitable character, v

The blank, flat sheet, provided with its flexible transparent portionflatly seamed to it, as above described, is in condition to be and istreated by processes of manufacture the same asthough it containednotransparent window, which fact greatly cheapens the cost. And thefinished article is cheap, strong, and much less liable to breakage thanthe ordinary rectangular transparent sided sheet-metal vessel.

It will be noted that owing to the nature I of the transparent flexiblematerial, preferably celluloid, and to the method of securing She t ofmetal and a sheet of flexible.
